Structure and Morphology Properties of Nanoparticle Hematite Pigment from Lathe Waste

Abstract

Hematite coated PEG was synthesized by the sonication-calcination method. A variation of Na2CO3 is investigated to know the effect on structure and morphology. Characterization of samples are using X-ray fluorescence, X-ray diffraction, Scanning electron microscopy, and color reader techniques. XRF data showed that iron is the highest element in the precursor. The X-ray diffraction data confirm that Fe(OH)3, α-FeOOH, and Fe3O4 established at the sonication stage are then transformed into the α-Fe2O3 phase after calcination. The X-ray diffraction data also was found that α-Fe2O3 at 0.5 M formed with the highest crystallinity degree. The scanning electron microscopy showed that the particle's shape is spherical, bar-shaped, and aggregate. However, the distribution of particles is not uniform and still displays agglomeration. The Color reader shows the highest degree of lightness obtained is at 1 M variation.

Effects of physical treatments on size particle and nutritional properties of bone powder from Pangasius sp

“…Previous studies of fishbone powder using physical treatments were used many methods such as wet bead mill, speed homogenizer, grinder, blender, steam explosion, and superfine grinding [7,8,10,12,14,15]. Besides all these physical treatments, temperature and sonication are also known to affect structure properties and particle size reduction [16,17]. Guo et al [18] conducted previous research on using a sonicator to treat fishbone powder.…”
